Question

我有HTML变量存储值835我希望在835之前应该有$这样显示价值$ 835。

same_vaccination_severeei_unvaccinated_val_1.value =  ((parseFloat(mixed_population_ci_unvaccinated_val_1.value) * parseFloat(if_influenza_severe_unvaccinated_val_1.value)/10000)*100).toFixed(2) + $;

Answer 1

same_vaccination_severeei_unvaccinated_val_1.value = '$' + ((parseFloat(mixed_population_ci_unvaccinated_val_1.value) * parseFloat(if_influenza_severe_unvaccinated_val_1.value)/10000)*100).toFixed(2);

Answer 2

试试这个

same_vaccination_severeei_unvaccinated_val_1.value = "$"+((parseFloat(mixed_population_ci_unvaccinated_val_1.value) * parseFloat(if_influenza_severe_unvaccinated_val_1.value)/10000)*100).toFixed(2);
